HEATER FOR GAS-JETS.

Application filed October 30, 1906.

To all whom it may concern.-

Be it known that 1, JAMES W. ALLEN, a citizen of the United States, residing at Heading, in the county of Berks, State of Pennsylvama, have invented certain new and useful 1 Improvements in Heaters for Gas-Jets; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention has relation to heaters adapted to be employed over an illuminating or other gas-jet, to not only heat a room in which the device is employed, but also to boil water or do cooking in a kettle, pan or pot on top of the heater.

The heater'in the present case is composed of an upper and a lower section, and each of the two sections is composed of a plurality of members one within another, the inner members being corrugated to increase their radiating surface and also open on their to s to allow of the ascension of the currents of mat, and all of the members being through the sides at their upper en s to allow the heat to escape laterally from them.

The nature of the invention is embodied in the device shown in the accompanying drawings, forming a part of this specification, in view of which the said invention will first be described with respect to its construction and mode of operation and then be pointed out in the subjoined claims.

Of the said drawingsFigure 1 is a vertical sectional view of the heater and its supporting bracket, Fig. 2 is a horizontal sec.

tional view on the line 22 of Fig. 1, Fig. 8 is a fragmentary view hereinafter more particularly referred to.

In the drawings 10 designates the lower section and 11 the upper section of the heating device. The lower section is composed of three cylindrical, or substantially cylindrical, members one arranged within the other.

12 designates the inner member of the lower section which is composed of a hollow cylinder of metal corrugated circumferentially from top to bottom being smaller at the top than at the bottom. Said cylinder 12 is provided in the upper part with holes or perforations 1.3. .It is also provided with a top or covering 16 which is likewise perforated so as to allow the heat entering the bottom to escape through the holes in the sides as well as through the top.

which is larger in circumference than the member 12 and also longer than said member. Member 17 like the member 12, is provided in its upper part with perforations 18 formed through its sides and with a top which is also perforated. The member 17 is corrugated vertically or at right angles with the corrugations formed in the central member 12 so as to afford larger surface for the radiation of heat therefrom.

19 designates the outer member of the lower section which is made preferably in the form of a bell, and having perforations in its upper portion, as at 20, similar to the perforations formed in the members 12 and 17, and like the latter members, the outer or bell shaped member has a top with fine perforations formed therein.

22 designates a rod or bolt reduced at its upper end. and screw threaded, said reduced portions extending through holes formed in the top of the members 12, 1-7 and 19, said tops resting one after another on the shoulder of the reduced portion of said rod. On the upper member a nut 24 is turned thereon to secure the tops of the several members together. The bolt 22 extends down where it is provided with an inverted cone shaped device 25 so that the heat ascending within the inner member 12 will be deflected by said inverted cone-shaped device outwardly of the sides of said member.

36 designates the inner tube of the upper section, the lower end 37, of which is reduced by having its sides inclined inwardly, and the upper end of which is secured through an annular lateral flange, centrally to the upper end of the intermediate drum or member 29, of twice the diameter of the tube 19.

The drum member 29 extends considerably below the lower end of the tube 36, and projects telescopically, over the top of the upper end of the outer member 19. The members 19 and 29 are connected by pins 27 extending laterally from the upper part of the member 19, which pins are moved with said member through the vertical portion 31 and horizontal portion 32 of slots made in the margin of the lower end member 29 (see Fig. 3,) the said connection being of a kind commonly called a bayonet joint.

The intermediate member 29 is rovided externally with a lateral annular ange 34 opposite the up er end of the outer member 19 which lateral fiange has a vertical rim or 17 designates an intermediate member flange 34 connected ,with it.

The outer drum is secured upon the rim 34 by a bayonet joint connection the same as before described, through the medium of pins 21 extending laterally from the said rim through slots formed in the bottom portion of the outer member similar to those shown in Fig. 3.

An imperforate cap, 31, is arranged on the top of the outer drum 35 and is bound thereon by rod 31 having heads on their 'upper ends resting on the upper surface of the cap, the lower screw-threaded ends of the said rods extending through holes formed in the lateral flange 34, and having taps turned on their lower ends.

The upper ortionsof the tube and drums will have ho es made through their sides through which any ascending heat may es cape. The tube and intermediate drum are corrugated vertically.

The bell shaped member 19 of the lower section is provided on its upper side with a hook-shaped device, 37, adapted to be engaged ina perforation, 38, shown by dotted lines, as formed through the outer end of a jointed swinging bracket, 39, adapted to have its base 40 secured to a wall or post so that the heating device as a whole may be supported on said bracket 39 andswung out of the way or moved around over a burning gas-jet in such position that the point of the inverted cone 25 of the bolt 22 will be centrally over said burning jet.

either out of the side perforations of the upper portions of the several members of the lower sections or through the perforations in the top thereof.

By the method and means described I am enabled to collect, as it were, all of the units of heat ascending from the gasjet and radiate and distribute the same laterally. The upper surface of the cap to the upper section may be utilized for heating water or cooking food by placing a kettle or pan on the top of the heater.

It is to be noted that my improved heater is not confined to use on a gas-burner, but may be employed in connection with a jet or other burner of any kind.

Where the flame from the burner is employed for illuminating purposes it will be seen that the lighting properties of the said flame will not be interfered with by the use .of my heater in connection therewith excepting directly above the jet-burner where the shutting out of the light will be of little consequence.

It is recognized that changes may be made in the form and arrangement of parts of the invention without departing from its general nature or spirit.

What is claimed is- 1. A heat radiator for gas jets comprising an inner bell-shaped member corrugated circumferentially, an intermediate bell-shaped member corrugated vertically, and an outer bell-shaped member, the outer members being of larger diameter than the next inner member, and each of said members being perforated, substantially as set forth, for the escape of heat therethrough.

2. In a heat radiator, a section comprising a plurality of bell-shaped drums of varying diameter, one inclosed within another and of graduated lengths, the outer drums being longer than the inner drums, and all of the drums being perforated through the upper portions of their sides, combined with a second section arranged above the first, also composed of a plurality of drums arranged one within another, each of said drums being perforated for the escape of heat therethrough. I

In testimony whereof, I aflix my signature, in presence of two witnesses.

JAMES W. ALLEN.
